APPARATUS FOR MAKING THE TOP CLOSURES OF ONE-PIECE LINERS FOR CANS OR OTHER RECEPTACLES.

Application filed March 19, 1923. Serial No. 626,112.

In my Patent No. 1,436,748 the one-piece liner and apparatus for making and setting same are fully described.

The present invention has for its object to provide apparatus for folding down over the contents of the receptacle the projecting part, or the division of the liner prearranged for making the top closure.

For the purposes of disclosure and demonstration, I have selected a simple variety of the invention and describe same with the understanding that I am not to be limited to the specific form shown as follows:

Fig. 1 is a view in elevation of a can and liner after the first folding operation has been made.

Fig. 2 is a plan view and section indicated by the dotted line 22 Fig. 1.

Fig. 3 is a view in elevation of a can and liner after the second operation of folding has been performed.

Fig.5 is a view in elevation of a can and liner after the third folding operation has been performed.

Fig. 6 is a plan view and section indicated by the line 66 Fig. 5.

Fig. 7 is a view in elevation of a can and liner after the last folding operation has been made with. the top closure completed, the liner folded over the contents slightly below the top of the can.

Fig. 8 is a plan view of a can with completed onepiece lining.

Fig. 9 is a view of apparatus in elevation and section indicated by the line 9 9 Fig. 10.

Fig. 10 is a plan view of apparatus and section indicated by the line 1010 S) with those parts above the section plane being shown in dotted lines and certain parts below being cut away to show some of the parts in full lines which. obscured from view, otherwise would be shown in dotted lines.

A support or frame may be provided with table 11 with horizontal members 12, 13 and 14 and vertical members 15 and 16.

Sprocket wheels 17 and 18 mounted on the horizontal shaft 19, 2'0 and 21 mounted on horizontal shaft '22 and wheels 23, 24, 25 and 26 mounted on vertical shafts 27 and 28 are revoluble with corresponding shafts in respective bearings.

For convenient reference the sprocket wheels mounted on horizontal shafts and revolving in vertical planes will be referred to as vertical wheels, and wheels mounted on vertical shafts revolving in horizontal planes will be referred to as horizontal wheels.

Chains 29 connect the vertical sprocket wheels and chains 30 and 31 connect the 1101- izontal sprocket wheels.

All of the wheels are of the same pitch and same number of teeth.

Transmission of power may be applied and governed by the tight and loose pulleys 32 and 33.

Miter gears 34 and 35 provide synchronous motion to the corresponding sprocket wheels and chains.

Corresponding linksof the vertical chains are connectedby chain bars 36, upon which the folder bars 37 are mounted to slide horizontally.

Each of the folder bars aforesaid supports two followers 38 and 39 and a folder 40.

The followers aforesaid are revoluble on their respective pintles 41 and 42 and the folders are mounted to slide vertically on the pins 43. i

1Vhen the folders are in their positions they rest and slid-e on the top of the table as shown at 44, and when elevated are held by their weight together with the weight of the followers always in a vertical position as shown at 45.

The lower section slide in guides 46.

Certain links of one of the horizontal chains are provided with attachments 47 which include each two rounded members 48 and 49.

Certain links of the other horizontal chain are provided. with attachments 50 and to these a belt 51 may be fastened.

Supports 52, sliding-1y held by the frame members 53 and 54, carry the turner bar 55 and the can turners 56.

Springs 57' maintain the turner bar and can turners aforesaid gently pressing toward the center of the machine.

Racks 58, 59 and 60 9) may be placed in any suitable way to prevent sagging of the chains between the sprockets.

Cams 61 and 62 co-operate with the folof the vertical chains (shown only in Fig.

lowers aforesaid to slide the folders and supports back and forth across the table as required.

Can rails 63 are provided to support the cans while passing through the machine, and the overflow pan 6 f is set to receive surplus liquor which may be forced from the cans during the folding operation and returned to the brine tank, if brine is used.

Entrance guards 65, leading from the can line, position the cans to be taken up by the conveyors.

Guard spring 66 may be provided to permit the release of one can and to guide the next following can to the take-up position.

Discharge belt pulley 10 only) 67 is revolubly mounted to carry the can discharge belt 68 operated by any transmission arrangement to receive the cans from the can rails aforesaid and deliver same at a slightly greater velocity than that of the can conveyors.

The onepiece liners made and set in the cans with that part of the liner prearranged for the top closure projecting above the top of the can are shown at 69.

The cans are received on the feed apron at 7 O and are taken up by the conveyor attachments at 71. A, B, C and D represent the folds or stations at which folds are made.

In operation, cans with the one-piece liners 69, Fig. 10, made and set therein as fully described in my Patent 1,436,748 having the divisions extending above the can tops as prearranged for the top closures are received at 70 from the can line (not shown) and are forced by the usual moving belt of the can line to take position in the passage way to be taken up by the conveyor attachments 47 at 71.

The conveyor attachment 47, moving in a counter clockwise direction takes up the can at 71, Fig. 10, and forces the same past guard spring 66 which gently acts centrally against the can.

As soon as a can is taken up by one of the conveyor attachments 47, another can is forced into position 71 by the line belt (not shown) and thus the can feed operation is constantly repeated.

In the drawing the section plane indicated by the line 1010, Fig. 9, cuts the lower rims of the four vertical sprocket wheels as shown, also one of the folders 40 and also a pair of the followers 38 and 39. To avoid confusion, only that part of the vertical chain below the section plane has been shown.

It will be observed that the movement of the cans with that of the feed belt 51, the conveyors 47 and the folders 40 is longitudinally synchronous.

The cans in passing rest upon the rounded points 48 and 49 of the conveyors 47, for

which points rollers may be substituted if desired, and are gently pressed thereupon by action of the springs 57 co-operating with the turner bar 55 and the turner-bar supports 52 slidingly mounted in the frame members 53 and 5d.

The cans pass from the feed apron (not shown) at 71 to the can rails 63 and are sup-- ported thereby during passage of the cans through the machine.

When a can and the corresponding folder 4:0 reach station A, Fig. 10, the follower 38 co-operates with the cam 61 to move the folder bar 37 together with the folder l0 transversely, or across the path of the cans, until the central axis of the folder approximately coincides with the axis of the cans. The bottom of the folder -l() slides over the top of the table 11 and the curved or bevelled bottom of the folder 4L0 facilitates entrance into the can. The projecting division of the folder is thus bent or folded down as shown in Figs. 1. and 2 the fold having been made in the direction indicated by the arrow A, Figs. 1 and 2.

it will be observed that by reason of the vertical movement of the folder 40 on the folder-pin e3 together with the weight of the folder, that the fold of the liner is pressed below the top of the can; also, that the amount of depression can be regulated by the screw and nut on the folder-pin 43.

As the can advances longitudinally, the left follower 89 co-operates with the left cam 62, Figs. 9 and 10, to move the folder transversely back upon the table and the curved or bevelled bottom of the folder slides over the flange top of the can and readily rises to the higher level of the table 11. WVhen the return follower 39 has traversed the cam 62, the folder 40 will have returned to its original transverse position.

The can advancing now reaches the first can-turner 56 after station A, Fig. 10.

The turner 56 may consist of any suitable material which presents to the moving can a stationary surface and causes the surface of the can to roll thereupon.

For example, a No. 1 can is about 8 inches of outer circumference, and therefore when four folds of the liner are to be made, the turners should be 2 inches wide. Thus a No. 1. can would roll 2 inches on the turner surface or turn 90 degrees, as it should turn when four folds are desired. If a greater number of folds are desired, or cans of different diameters used, the turners would be regulated accordingly.

At stations B and G, the foregoing operations are repeated.

At station D the fourth and last fold is made, after which no turning of the can is required.

After passing station D, the cans With the "down over the contents of the top closures completed, the folds having been neatly made preferably about of an inch below the top of the can, may be delivered upon the usual discharge disc, or upon a discharge belt as shown at 68 operating upon pulley 67 which should move at a slightly higher speed than that of the conveyor chain to free the cans from the conveyor attachments. The folders return to the initial position 71 and the synchronous conveyors take up other cans repeating the cycle continuously.

As the diameter of the folder is very nearly the same as the diameter of the receptacle, the folds stay put whether wet or dry. When brine is, used, the overflow may be conducted back to the briner by the pan 64:.

With slight modifications, the machine will operate with square or other shapes of cans or cartons.

Having shown a simple variety of the invention which will suggest many others of the same species, I desire to protect by Letters Patent all combinations which include all of the same or equivalent elements set forth in each of the following combinations claimed:
